Casey's point is a big one, and one we try to stress here at MAB. When transitioning to a fullbody it's essential that a lifter not rush into it. Start with a moderate weight and build slowly.

I personally spent 4-6 months trying (and failing) to use a fullbody approach because I wanted to enter it with heavy weight, guns blazing. Finally, after a dozen starts and stalls, I dialed things back a bit.
